Thank you, I read this article. My problem is that, although the vendor version is 10.8, it only contains ENСRYPTION_SEEDS (got them by flexlm-7-x-11-4-seed-extraction.pdf), and uses 20 digit keys. I tried to create 12-digits keys in SDK 7, and then run "lmcrypt -verfmt 5 -longkey", but this keys dont work.

I promise that I have read the FAQ and tried to use the Search to answer my question.
